Question

我想用一个特定的单词替换多个同义词。

<?p

$a = array(
'truck',
'vehicle',
'seddan',
'coupe',
'Toyota',
);
$b = array(
'car',
'car',
'car',
'car',
'Lexus',
);
$str = '

Honda is a truck. 
Toyota is a vehicle. 
Nissan is a sedan. 
Scion is a coupe.

';
echo str_replace($a,$b,$str);
?>

结果：本田是一辆汽车。雷克萨斯是一辆车。日产是一辆车。 Scion是一辆汽车。

有人能给我一个干净的方法，用“汽车”代替“车辆，卡车，轿跑车，轿车”而不是我单独更换所有4个。谢谢。

Answer 1

$a = array( 'truck', 'vehicle', 'seddan', 'coupe' );
$str = 'Honda is a truck. Toyota is a vehicle. Nissan is a sedan. Scion is a coupe.';
echo str_replace($a,'car',str_replace('Lexus','Toyota',$str));

Answer 2

您应该使用strtr

echo strtr($str,array_combine($a,$b));

或者只需将$a和$b合并为一个数组

$ab = array('truck' => 'car','vehicle' => 'car','sedan' => 'var','coupe' => 'var','Toyota' => 'Lexus');
echo strtr($str, $ab);

输出

Honda is a car. 
Lexus is a car. 
Nissan is a car. 
Scion is a car.

Answer 3

像

这样的东西

$a = array( 'truck', 'vehicle', 'seddan', 'coupe' ); 

$str = 'Honda is a truck. Toyota is a vehicle. Nissan is a sedan. Scion is a coupe.'; 

echo str_replace($a,'car',$str);

应该工作。

这样的事情会产生预期的结果：http://pastebin.com/xGzYiCk3

$text = '{test|test2|test3} some other stuff {some1|some2|some3}';

输出：

test3 some other stuff some1
test2 some other stuff some2
test3 some other stuff some3
test3 some other stuff some1

Answer 4

我找到了一个非常简单的解决方案来替换字符串中的多个单词：

<?php
 $str="    Honda is a truck. 
Toyota is a vehicle. 
Nissan is a sedan. 
Scion is a coupe.";


$pattern=array();
$pattern[0]="truck";
$pattern[1]="vehicle";
$pattern[2]="sedan";
$pattern[3]="coupe";



$replacement=array();
$replacement[0]="car";
$replacement[1]="car";
$replacement[2]="car";
$replacement[3]="car";



echo str_replace($pattern,$replacement,$str);?>

输出

  Honda is a car. 
Toyota is a car. 
Nissan is a car. 
Scion is a car

使用此脚本，您可以根据需要替换字符串中的多个单词：

只需将单词（您要替换的单词）放在模式数组中，例如：

     $pattern[0]="/replaceme/";

并将替换数组中的字符（将用于代替替换字符）放置，例如：

      $replacement[0]="new_word";

快乐的编码！

Answer 5

用于将短语替换为其他短语（一次多个）。您可以将数组作为参数传递给str_replace()

// Provides: You should eat pizza, beer, and ice cream every day
$phrase  = "You should eat fruits, vegetables, and fiber every day.";
$healthy = ["fruits", "vegetables", "fiber"];
$yummy   = ["pizza", "beer", "ice cream"];

$newPhrase = str_replace($healthy, $yummy, $phrase);

用Str_Replace替换多个单词
